3 Claims.

3 My inventionrelates to attachmentsfor stirring ice cream orthe likewhile the cream or like substance is being frozen in mechanical req'frigerators, and'the primary object of. my present invention isimprovements "over my ice cream making attachment for mechanicalrefrigerators,

filed in the United States Patent Office September "26, 1934, Serial No.745,579, patented Nov. .17, o 1936, No.*2,06.l,077,"and the objects ofthe im- "IO provements are? First, to provide a shiftable paddlearrangement in which the paddle members rest on the bottom of thefreezing receptacle and are guided by the bottom and sides of saidreceptacle;

Second, to provide a receptacle for freezing ice "cream in mechanicalrefrigerators with a single central partition or dividing paddle;

Third, to provide a receptacle for mechanical 4 refrigerators in whichthe upper edges of the I20 ends ofthe receptacle as well as thepartition are curved to aid in mixing the contents of the receptacle aswell as keeping the contents from slopping out, thus eliminating anynecessity for a'cover for the receptacle;

Fourth, to provide an attachment of this class to which the operatingarm is connected with a relatively long centrally positioned portionwhich prevents tilting of the shiftable paddles; and

Fifth, to provide an ice cream making attach- 30 ment for mechanicalrefrigerators that is very simple and economical of construction andoperation, very efficient in its action, and which will not readilydeteriorate or get out of order.

With these and other objects in view as will appear hereinafter, myinvention consists of certain novel features of construction,combination and arrangement of parts and portions as will be hereinafterdescribed in detail and particularly set forth in the appended claims,reference 40 being had to the accompanying drawing and to the charactersof reference thereon which form a part of this application, in which:

Figure l is a longitudinal sectional view of my attachment along theline l--l of Fig. 2 and 45 showing some of the parts and portions inelevation to facilitate the illustration; Fig. 2 is a top or plan viewthereof showing some of the parts and portions fragmentarily, and Fig. 3is a transverse sectional view from the line 3-3 50 of Fig. 1.

Similar characters of reference refer to similar parts and portionsthroughout the several views of the drawing.

The freezing receptacle I, shiftable paddle 55 members 2, 3, 4 and 5,shiftable paddle member connecting bars 6, l and 8, pitman members,crank wheel l0, crank wheel shaft ll, and crank wheel support l2,constitute the principal -parts and'portions of my ice cream makingattachment L;

tionary paddle member lh which is provided with oppositely curved upperedges li and I and it will be noted that the upper edges of the sidemembers lb andlc extend upwardly some distance past the upper edges ofthe ends and partition'lh. Thesecurved upper edges If, l'g, li

and I7 turnthe contents of the receptacle with the movement of thepaddle members 2, 3, 4 and 5 causing portions of the contents to turnupsidedown and therefore provide additional mixing of the contents ofthe receptacle and also prevent slopping out at the ends, and theextended side members lb and lo prevent slopping over at the corners.

The shiftable paddle members 2, 3, 4 and 5 rest on the bottom la. andare guided thereby and the ends rest against the side members lb and laand are guided thereby. The upper corners of said paddle members arecurved at 2b, as shown best in Fig. 3, to provide more clearance for thecontents 'at the ends to prevent the contents slopping over, and eachpaddle member may be provided with holes therethrough, as shown in Fig.3. The members 2 and 3 are connected by means of a bar 5 and the members4 and 5 are connected by means of a bar 1, and the bars 6 and T areconnected by a bar 8, all as shown in the drawing.

It will be here noted that the shiftable paddle members 2 and 3 areadapted to reciprocate between the partition or stationary paddle memberiii and the end le, while the paddles 4 and 5 are adapted to reciprocatebetween the partition or stationary paddle lh and the end Id, and allconnected together and bridged by the bar 8 over the partition lh. Thisassembly of shiftable paddle members is reoiprocated by means of apitman member 9 which is provided with a vertical portion 9a which isslightly tapered and fits into a hole 8w in the enlarged portion of themember 8 and then extends downwardly into an enlarged portion 2a of thepaddle member 2, as

shown best in Fig. 1 of the drawing, thus providing considerable lengthof bearing and extending down to near the middle portion of the paddlemembers assembly and thus preventing tilting of the paddle members whilethey are reciprocating. This pitman member 9 is provided with a pitmanhead 9b which fits on a lug Illa on the crank wheel H]. The crank wheelI is mounted on a shaft H which shaft is revolved by any mechanicalmeans, such as a motor, not shown. The crank wheel l0 and shaft II aresupported by means of a support I2 which is secured to one end of thereceptacle l by means of threaded lugs Hat and wing nuts I217. Thesupport 12 is provided with a right angle turn He at its upper end whichforms the support for the wheel Ill and shaft I l,

Though I have shown and described a particular construction, combinationand arrangement of parts and portions, I do not wish to be limited tothis particular construction, combination and arrangement but desire toinclude in the scope of my invention the construction, combination andarrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In an ice cream making attachment for mechanical refrigerators, afreezing receptacle consisting of a box like member open at its upperside and provided with inturned portions at the upper edge of its' ends,a transverse partition extending across said receptacle at the middleand provided with oppositely disposed turns at its upper edge formingseparate compartments in said receptacle,apair of shiftable paddlemembers in each compartment, each shiftable paddle member being whollyvertical to its'full height and resting on the bottom of said receptacleand wholly supported by said bottom, said shiftable paddle members beingless in height than said receptacle and a single bridge connecting saidpairs of paddle members only and raised to pass over said partition.

2. In an ice cream making attachment for mechanical refrigerators, afreezing receptacle consisting of a box like member open at its upperside and provided with inturned portions at the upper edge of its ends,a transverse partition extending across said receptacle at the middleand provided with oppositely disposed turns at its upper edge formingseparate compartments in said receptacle, a pair of shiftable paddlemembers in each compartment, each shiftable paddle member being whollyvertical to its full height and resting on the bottom of. saidreceptacle and wholly supported by said bottom, said shiftable paddlemembers being less in heighth than said receptacle, a single bridgeconnecting said pairs of paddle members only and raised to pass oversaid partition, crank wheel and pitman means for reciprocating saidshiftable paddle members connected therewith through said bridge.

3. In an ice cream making attachment for mechanical refrigerators, afreezing receptacle provided with a transverse partition thereinprovided with oppositely disposed curved portions at its upper edge,shiftable paddle members mounted in said freezing receptacle on oppositesides of said partition wholly supported by the bottom of saidreceptacle and raised bridge means connecting said shiftable paddlemembers on opposite sides of said partition and extending over saidpartition, and crank wheel and pitman means connected with said bridgefor reciprocating said shiftable paddle members.
